“…Objective methods aim to collect and analyze objective data using different devices, such as pressure mats, electroencephalographs, and electromyographs. The comfort levels of subjects can be obtained by analyzing their movements and posture (Apostolico, Cappetti, D'Oria, Naddeo, & Sestri, ; Brenner, ; Greghi et al., ; Lueder, ; Rossi et al., ), pressure measurements (Fujimaki & Mitsuya, ; Groenesteijn et al., ; Vergara & Page, ), electromyography (EMG) (Rodrigues‐de‐Paula‐Goulart & Valls‐Solé, ), and so forth.…”
